ABSTRACT

An approach for ontological policy based data collection, processing, and negotiation for data in view of analytics is provided. The approach searches one or more data sources for data related to a data request. The approach collects data related to the data request from the one or more data sources. The approach determines whether one or more attributes generated from the data request match one or more descriptors associated with the data related to the data request. The approach creates one or more annotated ontologies for the data related to the data request. The approach displays a hierarchical visualization of the one or more annotated ontologies for the data related to the data request. The approach updates the one or more annotated ontologies for the data related to the data request based, at least in part, on an evaluation of the quality of the one or more data selections.

BACKGROUND OF THE INVENTION

The present invention relates generally to data analytics, and more particularly to data collection, data processing, and negotiation for data in view of analytics based on ontological policies.

Ontology is a model for describing a world that consists of a set of types, properties, and relationships. Ontologies can represent entities, ideas, and events, along with their properties and relationships, according to a system of categories.

Domain ontology (i.e., domain-specific ontology) represents concepts that belong to part of the world. Particular meanings of terms applied to a domain are provided by domain ontology. For example, the word “card” has many different meanings. Ontology about the domain of poker may model the “playing card” meaning of the word “card”, whereas ontology about the domain of computer hardware may model the “video card” meaning of the word “card”.

Since domain ontologies represent concepts in a very specific and often eclectic way, they are often incompatible. As systems that rely on domain ontologies expand, they often need to merge domain ontologies into a more general representation. This presents a challenge to the ontology designer. Different ontologies in the same domain arise due to different languages, different intended usage of the ontologies, and different perceptions of the domain (based on cultural background, education, ideology, etc.).

SUMMARY

The method includes searching, by one or more computer processors, one or more data sources for data related to a data request. The method includes collecting, by one or more computer processors, data related to the data request from the one or more data sources. The method includes determining, by one or more computer processors, whether one or more attributes generated from the data request match one or more descriptors associated with the data related to the data request. Responsive to a determination that the one or more attributes generated from the data request match one or more descriptors associated with the data related to the data request, the method includes creating, by one or more computer processors, one or more annotated ontologies for the data related to the data request. The method includes displaying, by one or more computer processors, a hierarchical visualization of the one or more annotated ontologies for the data related to the data request. The method includes updating, by one or more computer processors, the one or more annotated ontologies for the data related to the data request based, at least in part, on an evaluation of the quality of the one or more data selections.

DETAILED DESCRIPTION

Embodiments of the present invention recognize that cloud data collection has limited capabilities with respect to the proper identification and selection of data for streaming, and as such, data providers often restrict data flow beyond a point of usefulness for relevant analytics. Embodiments of the present invention further recognize that smart tagging and fine granularity selection of data provides opportunities for data selection, data collection, and data negotiation between a data provider and a data consumer.

Embodiments of the present invention provide the capability to support a data provider with off-line policy based data auto-tagging and on-line fine granularity data tagging in view of custom data selection and data collection based on negotiations between the data provider and a data consumer. Embodiments of the present invention provide the capability to preprocess data in view of relevant analytics based on source preview data and ontological polices related to the relevant analytics. Embodiments of the present invention provide a hierarchical visualization of the ontology to allow the data consumer to investigate and select data related to the relevant analytics. Embodiments of the present invention provide the capability to notify the data provider of data requests to additionally manually configure the ontological polices. Embodiments of the present invention provide the capability for a data consumer to evaluate the quality of a particular data provider's data.

In the exemplary embodiment, user interface 108(b) is a conventional user interface for providing capability to a user of data provider 110 for communicating with one or more electronic devices. In one embodiment, data provider 110 may communicate with data service 106 via a user interface, such as user interface 108(b). In the exemplary embodiment, data provider 110 sends data, such as ticket data of a cloud system, to data service 106 for collection and processing for analytics.

In the exemplary embodiment, data consumer 112 may be, for example, a server computer system such as a management server, web server, or any other electronic device or computing system capable of sending and receiving data. In another embodiment, data consumer 112 may be a data center, consisting of a collection of networks and servers providing an IT service, such as virtual servers and applications deployed on virtual servers, to an external party. In another embodiment, data consumer 112 represents a “cloud” of computers interconnected by one or more networks, where data consumer 112 is a computing system utilizing clustered computers and components to act as a single pool of seamless resources when accessed through network 102. This is a common implementation for data centers in addition to cloud computing applications. In the exemplary embodiment, data consumer 112 includes user interface 108(a). In the exemplary embodiment, user interface 108(a) is a conventional user interface for interacting with one or more electronic devices. In the exemplary embodiment, data consumer 112 requests specific data and evaluates the quality of data provided for an analytic solution from data service 106 via a user interface, such as user interface 108(a).

In the exemplary embodiment, network 102 is the Internet representing a worldwide collection of networks and gateways that use TCP/IP protocols to communicate with one another. Network 102 may include wire cables, wireless communication links, fiber optic cables, routers, switches and/or firewalls. Server 104, data service 106, data provider 110, and data consumer 112 are interconnected by network 102. Network 102 can be any combination of connections and protocols capable of supporting communications between server 104, data service 106, data provider 110, and data consumer 112. Network 102 may also be implemented as a number of different types of networks, such as an intranet, a local area network (LAN), a virtual local area network (VLAN), or a wide area network (WAN).

In the exemplary embodiment, data service 106 is a software-based component capable of preprocessing data with respect to analytics at a source level (i.e., source preview data from a data provider) and a destination level (i.e., policies related to analytics requirements of a data consumer). In the exemplary embodiment, data service 106 supports a data provider, such as data provider 110, with off-line policy based data auto-tagging and on-line fine granularity data tagging in view of custom data selection and data collection based on negotiation between a data provider and data consumer, such as data provider 110 and data consumer 112. In the exemplary embodiment, data service 106 generates a hierarchical visualization of an ontology related to a data request, allowing a data consumer, such as data consumer 112, to investigate and select pertinent data for a particular analytic solution via a user interface, such as user interface 108(a). In the exemplary embodiment, data service 106 provides the capability to notify a data provider, such as data provider 110, of a specific data request to allow the data provider to manually configure an ontology related to the data request via a user interface, such as user interface 108(b).

In the exemplary embodiment, data service 106 utilizes historical data from past policies and how provider data was used to update ontological policies.

FIG. 2 a flow diagram depicting an exemplary process flow of a data service, such as data service 106 in FIG. 1, generally designated 200, for policy based data collection, processing, and negotiation for analytics, in accordance with an embodiment of the present invention.

In the exemplary embodiment, data service 106 collects provider data 202. In the exemplary embodiment, data service 106 collects provider data 202 from one or more data sources, such as data provider 110, where provider data 202 is a plurality of input data including, without limitation, big data, server data, log data, web forum data, deployment recipes, Computer Emergency Readiness Team (CERT) bulletins, documents, spreadsheets, comma-separated values (CSV) files, JavaScript® object notation (JSON), and extensible markup language (XML), etc., made available by a data provider, such as data provider 110. In one embodiment, data service 106 may collect provider data 202 from one or more data sources actively, for example, by extracting input data from a data stream. In another embodiment, data service 106 may collect provider data 202 from one or more data sources passively, for example, by receiving input data from the one or more data sources directly. For example, data service 106 may collect log data made available by a data provider via a data stream. In another embodiment, data service 106 receives provider data 202 from a data provider, such as data provider 110.

In the exemplary embodiment, data service 106 populates data descriptor template 204. In the exemplary embodiment, data descriptor template 204 is a configurable data descriptor template including one or more ontological descriptors defining a particular domain.

In the exemplary embodiment, data service 106 utilizes ontology engine 206 to create one or more annotated ontologies for the provider data 202. Data service 106 utilizes ontology engine 206 to associate data descriptors, ontology descriptors, and relevant user defined data policy rules to create one or more ontologies for describing the data and its various handling requirements. For example, in an information technology (IT) configuration domain, where a user defined data policy states “If IP belongs to Company A, and Password not compliant, then add Logs”, data service 106 will create one or more ontologies with preferred labels, such as “password”, and its related data, with “worklogs”, and its related data. Aspects of data service 106 and ontology engine 206 are discussed in further detail in subsequent Figures.

Data service 106 utilizes data filter 208 to clean data from the relevant one or more ontologies and ensure the data conforms to user defined data policy rules. Upon completion of data filtering, consumer data 210 is made available to a data consumer, such as data consumer 112. Aspects of data service 106 and data filter 208 are discussed in further detail in subsequent Figures.

FIG. 3 is a flowchart depicting the operational steps of a data service, such as data service 106 of FIG. 1, generally designated 300, for data selection and negotiation, in accordance with an embodiment of the present invention.

Data service 106 receives a data request (302). In the exemplary embodiment, data service 106 receives a data request from a data consumer, such as data consumer 112, where the data request includes data that the data consumer is interested in for a particular analytic solution. In the exemplary embodiment, data service 106 receives the data request via a user interface, such as user interface 108, or an application program interface (API), where the data request can be in a natural language format or a structured format, etc. For example, data service 106 receives a data request from a data consumer, such as data consumer 112, where the data request specifies data needed for a particular analytic solution, such as an end user administrator or service providers interested in dynamically analyzing their operation and business data for benefiting customers with augmented visibility into the business.

Data service 106 searches one or more data sources for data related to the data request (304). In the exemplary embodiment, data service 106 searches one or more data sources for available data related to the data request by generating attributes from the data request and searching the one or more data sources for available data related to the attributes (i.e., the data consumer's data requirements). In the exemplary embodiment, the one or more data sources can include, without limitation, data streams, server databases, the internet, one or more data providers, such as data provider 110, cloud service providers, data mining engines, and any other suitable data sources capable of providing data to a data consumer. In the exemplary embodiment, data service 106 generates attributes from the data request by determining one or more attributes that describe and identify data requirements requested in the data request, where the one or more attributes can include, without limitation, a keyword, a topic, a phrase, a file type, a file size, a domain specific descriptor, a collection of system data, a plurality of statistics, a plurality of consumer information, a plurality of employee information, and any other suitable attributes capable of describing and identifying available data related to a data consumer's data requirements.

Data service 106 determines whether attributes generated from the data request match descriptors associated with the data related to the data request (306). In the exemplary embodiment, data service 106 determines whether attributes generated from the data request match descriptors associated with available data related to the data request, such as descriptors in the data descriptor template of FIG. 2, by extracting one or more features of the available data provided by the one or more data sources (i.e., data descriptors), and comparing the one or more features against the attributes generated from the data request. Where at least one of the one or more features of the available data are related to at least one of the attributes generated from the data request, data service 106 determines that attributes generated from the data request match descriptors associated with the data related to the data request. Where the one or more features of the available data are not related to at least one of the attributes generated from the data request, data service 106 determines that attributes generated from the data request do not match descriptors associated with the data related to the data request.

In response to a determination that attributes generated from the data request match descriptors associated with the data related to the data request (YES branch, 306), data service 106 provides a hierarchical visualization of one or more annotated ontologies for the data related to the data request (312). In the exemplary embodiment, data service 106 provides a hierarchical visualization of one or more annotated ontologies for the data related to the data request, such as the one or more annotated ontologies created by ontology engine 206 utilizing the operational steps of flowchart 400 depicted in FIG. 4, by displaying the hierarchical visualization of the annotated one or more ontologies to a data consumer, such as data consumer 112, via a user interface, such as user interface 108(a), where the hierarchical visualization of the one or more annotated ontologies for the data related to the data request includes ontology descriptors organized in a hierarchy. In the exemplary embodiment, the one or more annotated ontologies are annotated with summaries of one or more documents from the data related to the data request, and the annotations conform to one or more modifiable policy rules (i.e., data provider policy rules and data consumer policy rules) for handling the data. In the exemplary embodiment, data service 106 displays the hierarchical visualization via a user interface, such as user interface 108(a), to allow a data consumer, such as data consumer 112, to investigate different exposed aspects of the data and make data selections based on data requirements for a particular analytic solution. The operational steps of data service 106 for creating one or more annotated ontologies for the data related to the data request is discussed in further detail in FIG. 4.

In response to a determination that attributes generated from the data request do not match descriptors associated with the data related to the data request (NO branch, 306), data service 106 sends a request for additional data related to the data request (308). In the exemplary embodiment, data service 106 sends a request for additional data related to the data request to the one or more data sources to evaluate the availability of any additional data related to the data request. In one embodiment, data service 106 may receive a notification from the one or more data sources that additional data related to the data request is available. In another embodiment, data service 106 may receive a notification from the one or more data sources that no additional data related to the data request is available.

Data service 106 determines whether attributes generated from the data request match descriptors associated with any additional data related to the data request (310). In the exemplary embodiment, responsive to availability of any additional data related to the data request, data service 106 determines whether attributes generated from the data request match descriptors associated with any additional data related to the data request by extracting one or more features of the additional data provided by the one or more data sources (i.e., data descriptors), and comparing the one or more features against the attributes generated from the data request. Where at least one of the one or more features of any additional data are related to at least one of the attributes generated from the data request, data service 106 determines that attributes generated from the data request match descriptors associated with the additional data related to the data request. Where the one or more features of any additional data are not related to at least one of the attributes generated from the data request, data service 106 determines that attributes generated from the data request do not match descriptors associated with any additional data related to the data request.

In the response to a determination that attributes generated from the data request do not match descriptors associated with the additional data related to the data request (NO branch, 310), data service 106 prompts to modify a data policy (320). In the exemplary embodiment, data service 106 prompts a data consumer, such as data consumer 112, to modify an existing data policy via a user interface, such as user interface 108(a), to facilitate an enhanced return on available data related to the data request. For example, data service 106 may prompt a data consumer to modify a data policy by broadening a type of data requested in a data request by adding additional criteria, or modify the data policy by specifying less restrictive data requirements. In one embodiment, data service 106 prompts a data provider, such as data provider 110, to modify an existing data policy via a user interface, such as user interface 108(b), to increase the quality and quantity of available data related to a data request. In one embodiment, responsive to a data consumer, such as data consumer 112, modifying an existing data policy via a user interface, such as user interface 108(a), data service 106 may search one or more data sources for data related to the data request (304). In one embodiment, responsive to a data provider, such as data provider 110, modifying an existing data policy via a user interface, such as user interface 108(b), data service 106 may search one or more data sources for data related to the data request (304). In one embodiment, responsive to a data consumer, such as data consumer 112, modifying an existing data policy via a user interface, such as user interface 108(a), data service 106 may store the updated data policy in a database to be leveraged by an ontology engine, such as ontology engine 206, for creating one or more annotated ontologies utilizing the operational steps depicted in flowchart 400 of FIG. 4. In one embodiment, responsive to a data provider, such as data provider 110, modifying an existing data policy via a user interface, such as user interface 108(b), data service 106 may store the updated data policy in a database to be leveraged by an ontology engine, such as ontology engine 206, for creating one or more annotated ontologies utilizing the operational steps depicted in flowchart 400 of FIG. 4.

In response to a determination that attributes generated from the data request match descriptors associated with the additional data related to the data request (YES branch, 310), data service 106 provides a hierarchical visualization of one or more annotated ontologies for the data related to the data request (312). In the exemplary embodiment, data service 106 provides a hierarchical visualization of one or more annotated ontologies for the data related to the data request, such as the one or more annotated ontologies created by ontology engine 206 utilizing the operational steps of flowchart 400 depicted in FIG. 4, where the hierarchical visualization of one or more annotated ontologies for the data related to the data request includes ontology descriptors organized in a hierarchy, where one or more annotated ontologies are annotated with summaries of one or more documents from the data related to the data request, and the annotations conform to one or more modifiable policy rules (i.e., data provider policy rules and data consumer policy rules) for handling the data. In the exemplary embodiment, data service 106 provides the hierarchical visualization via a user interface, such as user interface 108(a), to allow a data consumer, such as data consumer 112, to investigate different exposed aspects of the data and make data selections based on data requirements for a particular analytic solution.

Data service 106 receives one or more data selections (314). In the exemplary embodiment, data service 106 receives one or more data selections from data provided in the hierarchical visualization of the one or more annotated ontologies for the data related to the data request. In the exemplary embodiment, data service 106 receives the one or more data selections from input from a data consumer, such as data consumer 112, via a user interface, such as user interface 108(a).

Data service 106 performs filtering (316). In the exemplary embodiment, data service 106 performs filtering of the data from the one or more annotated ontologies for the data related to the data request utilizing a data filter, such as data filter 208 of FIG. 2. In the exemplary embodiment, data service 106 filters data from the one or more annotated ontologies for the data related to the data request based, at least in part, on the data consumer's data selections, a data consumer data policy, and a data provider data policy, to generate a subset of data based on a data policy and various preferences of a data consumer and data provider, such as data consumer 112 and data provider 110. In the exemplary embodiment, data service 106 cleans the data from the one or more annotated ontologies by applying modifiable data policy rules, such as the one or more user defined policy rules received in flowchart 400 of FIG. 4, from a data consumer data policy, a data provider data policy, or both, to ensure the data selections conform to data policy rules. For example, types of modifiable data policy rules may include prevention from association based on privilege and security, partial deletion or redaction, IF-THEN conditions, and aggregation of information, etc. In one embodiment, in response to filtering the data from the one or more ontologies for the data related to the data request (i.e., data selections comply with modifiable data policy rules), data service 106 provides conforming data to the data consumer.

Data service 106 prompts to evaluate the quality of the one or more data selections (318). In the exemplary embodiment, data service 106 prompts a data consumer, such as data consumer 112, to evaluate the quality of the one or more data selections (i.e., the provided data), where an evaluation of the quality of the one or more data selections can include, without limitation, ranking data source credibility, ranking data source prestige, ranking data source relevance to a particular domain, effectiveness of a data policy, and ranking the ratio of data updated by filtering. In one embodiment, evaluating may include ranking the one or more data sources (i.e., data providers) by a type, a quality, and a quantity of data provided. In one embodiment, data service 106 stores the evaluation of the quality of the one or more data selections in a database (not shown), such that data service 106 may utilize the evaluation as historical data for updating the one or more annotated ontologies.

Data service 106 prompts to modify a data policy (320). In the exemplary embodiment, data service 106 prompts a data consumer, such as data consumer 112, to modify an existing data policy to facilitate an enhanced return on available data related to the data request. For example, data service 106 may prompt a data consumer to modify a data policy by broadening a type of data requested in a data request by adding additional criteria, or modify the data policy by specifying less restrictive data requirements. In another embodiment, data service 106 may prompt a data provider, such as data provider 110, to modify an existing data policy to facilitate better evaluations and increase data consumer activity. For example, based on past evaluations of data quality and data quantity, a data provider may modify data policy rules to allow for less restriction on data being provided.

Data service 106 updates the one or more annotated ontologies (322). In the exemplary embodiment, data service 106 updates the one or more annotated ontologies based, at least in part, on historical data related to past data policies' impact on provided data, feedback on how the data was used by a data consumer for a particular analytic solution, and various rankings of data sources and provided data.

FIG. 4 is a flowchart depicting the operational steps of a data service, such as data service 106 of FIG. 1, generally designated 400, for displaying a hierarchical visualization of one or more annotated ontologies, in accordance with an embodiment of the present invention.

Data service 106 receives one or more user defined policy rules (402). In the exemplary embodiment, data service 106 receives one or more user defined policy rules, where the user defined policy rules are modifiable data policy rules for handling collection, preprocessing, dissemination, and selection of data. For example, user defined policy rules may include rules relevant to data privacy, data cost, data topology, and quantity of data, data characteristics, etc. In another example, user defined policy rules may dictate how data is handled with respect to constraints, synonyms, dependencies, etc. In the exemplary embodiment, the user defined policy rules are modifiable, such that a data consumer, such as data consumer 112, and a data provider, such as data provider 110, can refine the data policy rules to meet various needs. For example, a data provider, such as data provider 110, may modify user defined policy rules to further restrict the type and quantity of sensitive data collected for dissemination to a data consumer, such as data consumer 112, while broadening the type and quantity of less sensitive data collected for dissemination.

Data service 106 collects data from one or more data sources (404). In the exemplary embodiment, data service 106 collects data from one or more data sources, where data sources include, without limitation, a database, a data stream, a plurality of files, a plurality of documents, and a data mining service, etc. In the exemplary embodiment, data provider 110 can include one or more data sources. In the exemplary embodiment, data service 106 collects data based, at least in part, on a data request from a data consumer, such as data consumer 112.

Data service 106 extracts one or more descriptors from the data (406). In the exemplary embodiment, data service 106 extracts one or more descriptors from the data (i.e., collected data), where the one or more data descriptors function to describe and identify the collected data. For example, data service 106 may extract features from collected (i.e., available) data based on headers, typical regular expressions, internet protocol (IP) addresses, and logs, etc.

Data service 106 populates a data descriptor template for the data (408). In the exemplary embodiment, data service 106 populates a data descriptor template, such as the data descriptor template of FIG. 2, for the data with the one or more descriptors extracted from the data. Data service 106 employs automatic data tagging based, at least in part, on a given domain ontology, a particular set of data (i.e., collected data), and a data provider data policy.

Data service 106 determines one or more ontologies defining a domain for the data (410). In the exemplary embodiment, data service 106 determines one or more ontologies defining a domain for the data by discovering relevant ontology descriptors and associating the relevant ontology descriptors with related data descriptors from the collected data. For example, where data service 106 extracts a data descriptor “social security number”, data service 106 may discover relevant ontological descriptors, such as “SSN”, associate the relevant ontology descriptors with the related data descriptor “social security number”, and then determine one or more ontologies defining a domain for data related to social security numbers.

Data service 106 associates the one or more user defined policy rules with the one or more descriptors from the data (412). In the exemplary embodiment, data service 106 associates the one or more user defined policy rules with the one or more descriptors from the data by determining a level of relevancy between policy rules and data descriptors. For example, where a user defined policy includes rules related to sensitive and confidential patient information, data service 106 may determine a high relevance between those rules and collected data that includes patient health records, social security numbers, addresses, and contact information, etc. In response to a determination of a relevance between policy rules and data descriptors, data service 106 associates the one or more user defined policy rules with the one or more descriptors from the data for managing the retention, aggregation, and pruning of the data.

Data service 106 creates one or more annotated ontologies for the data (414). In the exemplary embodiment, data service 106 creates one or more annotated ontologies for the data by combining ontologies defining a domain for the data and concept related policy (i.e., user defined data policy rules) to describe the data and various handling requirements (e.g., synonyms, dependencies, constraints, privacy rules, etc.) depending on those concept related polices. For example, data service 106 may create an annotated ontology for data related to rates of healthcare incidents, where the annotated ontology may include data related to a type of healthcare incident (e.g., ER, trauma, oncology, checkup, etc.), but will exclude patient data (e.g., social security number, name, address, etc.) based on defined policy rules.

Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.
